Abstract
A low distortion amplifier arrangement includes an amplifier having an inverting input, a non-inverting input, and an output, a first impedance coupled between the output and the inverting input, and a second impedance coupled between an input terminal of the amplifier arrangement and the amplifier inverting input. An impedance network is coupled between the inverting and the non-inverting inputs of the amplifier. The impedance value of said impedance network substantially corresponds to the impedance value of the parallel connection of the first impedance and the second impedance, but with opposite sign. The gain of the amplifier arrangement is independent of the gain of the amplifier and corresponds to the ratio of the impedance values of said first and second impedances to produce an amplifier arrangement with a very low distortion.
